CUSTOM GAME ENGINES: A Small Study

a_plague_tale

WARNING: Article moved to separate repo to allow users contributions: https://github.com/raysan5/custom_game_engines

A couple of weeks ago I played (and finished) A Plague Tale, a game by Asobo Studio. I was really captivated by the game, not only by the beautiful graphics but also by the story and the locations in the game. I decided to investigate a bit about the game tech and I was surprised to see it was developed with a custom engine by a relatively small studio. I know there are some companies using custom engines but it's very difficult to find a detailed market study with that kind of information curated and updated. So this article.

Nowadays lots of companies choose engines like [Unreal](https:

Records DOM-events and replays them on demand. Nice for server side rendered pages: record during page-load, replay after all javascript was initialized.
/**
* EventRecorder
* @class
* @classdesc An EventRecorder can record and replay any event on any DOM node
* @param {string} [eventName=click] - Name of the events to record
* @param {class} [EventClass=MouseEvent] - The class that should be used to recreate the events
* @param {object} [context=self] - The context DOM element, the events should be fetched from
* @example
* // Create a recorder for click events
* const clickRecorder = new EventRecorder('click', MouseEvent, window);

IndexedDB Full Text Search (Proof of Concept)

This demonstrates the implementation of full text search for documents in Indexed DB.

  • Word-breaking and stemming is used to create a list of terms for each document.
  • Document records are annotated with the list of terms when added to the database.
  • A multi-entry index on the list of terms is populated.
  • A query is similarly processed into a list of terms.
  • A join over the terms is implemented using multiple cursors on the index.

The necessity of annotating records with the word list to populate the index is a limitation of the current Indexed DB API. A feature request to support custom
